COMBINED ROUTER AND WORK SUPPORT.

Application filed August 13, 1927. Serial No. 212,759.

, This invention relates to a support for routing machines, and likepower driven devices, and has for its primary object to provide acombined router and work support, comprising a table for directlysupporting the work, the said table being movable in different planes,and beingsupported by a pedestal for conveniently positioning the work.A further object is to provide a re.- ciprocable member, that supportsthe rout; ing machine, and renders the router movable towards and fromthe work in a vertical plane, said member being controlled in itsvertical-movements by a pedal, and being guided by means rigid to .thepedestal. A further object is to provide means for'mov- .ing the routerperpendicular to said mem-' ber and transversely of the table, forperforming routing work while the table is stationary, the table and thework being mov-- able longitudinally and circularly for efiectingrouting-work when the router is-held stationary. A further object is toprovide means for tilting the router relatively to the reciprocatingmember and the table, and

- complete machine showing thg router in the released position alsoshowing the pedal for lowering the router to the work supported by thetable. Fig. 2 is a side elevation taken in the direction of the arrow inFig. 1 showing the means for adjusting the router vertically a Y dhorizontally as well as for tilting the rou r in the vertical plane;Fig. 3 is a rear side elevation Fig. 4 is a top plan view; showing therouter, the table, and re lat-ed parts in the positions of Figs. 1, 2and ,3, also'showing by full lines and dotted lines difi'erent positlonsof the leverthat controls the horizontal movements of the router.

In the drawings, 2 .represents generally a edestal that supports all theparts of the evice, and being formed with a fianlgedbase 2', that may besecured to a floor.

estal comprises upper and, lower sections, 2 2, which are usually boltedtogether, as

at 2.: Section 2* is preferably T-shaped, one

arm 2 'extending forwardly and supporting the work-table, as 3, andrelated .parts, the

arm 2 extending rearwardly, and being formed with 'means 2, for guidinga. vertically reciprocable rod or-member 4, which supportsarouter 5 andother parts. Section 2 of the pedestal is provided with a similar arm2*, that guides the lower portion of the member 4. The lower end of rod4 is preferably hollow and is uided by an axially alining member 4, wose upper end telescopes said rod, the lower endof said guidememberbeing anchored in the base 2 (see Fig. 2) The rod 4 is reciprocated by apedal 6, which is pivoted between lugs 6 formed near the rear margin ofthe base 2',

by a-pin 6*. The body of the pedal is formed with an opening 6", whichloosely receives the pedestal 2', and its free end 6 extends forwardlywithin convenient reachof the operators feet. The pedal 6 is normallyheld released,as in Figs. 2 and 3, by a s ring 6, i

The rod 4 is pivotallyconnected to t e pedal by a yoke 7 the bottom andtop ends of the yoke being pivoted respectively to the pedal, as at 6,and to a split collar 7' which is clamped to the rod, and is renderedadjust"- able y a wing-bolt 7 for varying the strokes of the pedal. Therod 4 may be locked against vertical movement by a bolt 4, that controlsthe split guide 2. The rod 4 is still further guided and steadied by amember 8, one end thereof comprising a split collar. 8, which receivesand may be ad'ustably clamped to the rod, by a bolt 8*. e bod oftiiemember 8-part1ally encircles the pe esta and its forward end 8 is formedwith a slot that slidably engages a stationary guide-bar 8 carried bythe pedestal. The to l end of the member 4 is surmounted by a s ht head9 Which'is clamped to the rod by a olt 9,-and is provided with aforwardly facing zontal guide 10, by a bolt 9", the said guidehavingadepending slotted arm 10' on which is formedan angular perforatedlug 10".

The guide 10 is 'swingable vertically on the perforated lug 9 to whichis pivoted a horipivot 9 the extent ofthe slot in the arm 10.,

and is held in the adjusted'po'sitions by a bolt.9, which screws'into a'rearward extension 9 of the head,-the latter being formed with a similarangular-lug 9;- A screw 10" engages the lugs 9 and 10", and supplementsthe bolt 9 for holding the rear portions of the.head and guide rigidwhen adjusted. The top of the guide 10 is formed with spaced upwardlyprojecting threaded hubs 1010 a horizontally slotted boss 10, and also alaterally extending perforated arm 10. (See Figs. 2, 3 and 4.) The head9 and tor 5*, which may be supplied with current by Wires 5 -5", and isarranged to drive any suitable router-bit, as 5. The collar 5 may beclamped to the motor-casing, by a bolt 5. The rod 12 is reciprocatedhorizontally by a lever 13, which is ivoted by a bolt 13' to a laterallyextending ar 14; that is supported by the slotted boss 10. The lever 13is slidably supported by a guide-bar 15, that is rigidly mounted uponthe hubs 10-10, and said lever is operatively connected to the rods 12,

by a link 16, one end of the link being pivoted to the lever, by a bolt16', its opposite end being pivoted to a split collar 17,whichisadjustablyclamped to the rod 12, between the router 5 and thehead 9 (see Figs. 3 and 4). The rearward movements of the rod 12 and therouter 5 are controlled and may be varied by the clamp 17, the forwardmovements of said rod may be likewise controlled by a similar clampingmember 17 which is adjustably mounted on said rod beyond the, rear endof the guide 9, as may be understood by consulting Figs. 2 and 4, Thearm 1O of guide 10 supports a short rod 10", which'supplements the guide10 for steadying and preventing accidental rotating of the rod 12. Therear end of rod 10 slidably engages a forked arm 17*, which is integralwith the stop 17 (see Figs. 3 and 4). The downward movement of the rod 4is controlled by a gage-rod 18, whose bottom, end is anchored in theguide 8, the rod thence passing loosely through and being guided by thearm 2 of the pedestal,

and its top-end engaging the under-side of the head 9. The rod .18passesloosely through a sleeve 18' supported by the arm 2, and'upon which isrotatably mounted a gage member 18, the latter being fitted with acircular arrangement of ad ustable upwardly facing gageestuds, as 18"(see Fig. 2), of different height. Near the head 9 the rod 18 is fittedwith a similar adjustable gage member 18, which may be made rigid to thered by a setscrew 18", and has a depending gage-stud 18,

which contacts with the studs 18" when the latter are selectivelydisposed in the path of the stud 18, for accurately gaging the diflerentdepths of the routing by the bit 5, as shown in Fig. 2.

The arm 2 of the pedestal is formed with lateral flanges 19, to which isremovably attached a split head 19 that supports thetable 3 and relatedparts. The head 19 is formed with correspondingly slotted flanges 19(see Figs. 1,2 and 3), the said parts being adjustably connected bybolts 19*. By this arrangement the table 3 may be tilted in a verticalplane the extent of said slots. The head 19 is bored out vertically, asat 19, for pivotally supporting a plate or member 20, whose medialportion is formed with a depending hollow hub 20 that journals in saidbore (see Fig. 2), the said hub being clamped in said head at will, by abolt 19 The member 20 is provided near its four corners with uprightbosses 20-20 which respectively support similar parallel guide-rods21-21, said rods being rigidly connectedto the member by bolts21. Thetable-is disposed above the plane of the rods 2121'. and its undersideis formed with depending guide-lugs 3'-3 that slidably engage the saidrods, and by which the table may-be moved longitudinally. The tableretains its position on the guide-rods mainly by gravity, but it ispreferably positively held from accidental detachment by a guide member22, which frictionally engages the underside of the rod 21 and isadjustable by means of a bolt'22 which may be employed for locking thetable against said endwise movements (see Figs. 1,2, and 3). The forwardmargin of the table is formedwith an upwardly projecting lipv againstwhich certain work may be disposed. The top-face ofthe table 3 is formedwith an inverted T- shaped groove 3, similar to the tables of thewell-known milling machines, for attaching various work supporting andsecuring devices (not shown). The table 3 isrcciprocated on rods 21-21'by a lever 23, the latter passing beneath and projecting beyond the rearedge of the table, and its rear-end is pivoted to a support 24, by abolt 24, the support,

2-tbeing bolted to the bosses 20 of plate 20, as shown in Figs. 1, 2 and3. The medial portion 23 of lever 23 is formed with a longitudinal slot23 which is engaged by a pin or stud 3 (see Fig. 2), that depends fromthe bottom of the table, and by which the table is shifted .endwise bythe corresponding movements of the lever 23 (see Fig. 4). The table 3may be partially rotated in a vertical plane to the extent of the slotsin the flanges 19, by the loosening of bolts 19". (see Figs. 1 and 1).Below the plate 20 is disposed a stationary circular scale 25, havingdegree gradua'tions readable .in opposite directions from a central .orzero mark, for accurately adjustingthe table in a horizontal plane.- Thereading of the scale is facilitated by a pointer 25' which is rigid tothe bottom of plate 19 and is therefore movable with said late and table3. '26 represents a block any suitable work which is mounted onthe table3 within range of the bit 5 (see Figs. 1 and 2 when the latter islowered by depressing t e pedal 6'.

My device is capable of performing many dilferent routing operations inconnection with a g'reat'variet'y of work. a The tool 5 is adapted tocut at many difl'e'rent angles as Well as in straight and circularpaths, within the relatively broad ranges of the several ad justingmeans, without requiring removal or substitution of any of the parts ofthe device,

except therouting-bits. And all adjust-' ments may be made readily andaccurately by operators of ordinary skill.
